Providing heat for BRF jars

First time doing this, never grown mushrooms before. Still cold up north. The only place for me to hatch a few is in the garage, which is pretty much a constant 55º. I am trying out a warming mat in a container. I had to line the lower part of the container with some foil-covered bubble wrap to help insulate and allow the heating mat to maintain 75º without being on constantly.
It seems to be working very well right now, and I like having some precise control of the heat.

I kinda cooked my cakes and stuntted them by having my incubator on a heading pad in between towels. I use it still to hear my closet but I have shelves now so it's raised 3 inch's off of it and it works perfect.

You don't need electricity to grow mushrooms ever, that just gets in the way.

I've heard of good results using an aquarium heater and monotubs. You heat the water that acts as the constant heat source and another container in that holds your jars. Might work for your area. I read about it somewhere on here. I like matheas's thinking though. Cool concept and must be true because mushrooms have been cultivated far longer than we have had access to electricity. Good vibes to you and your grow.

I like that idea also - next time I will just wait until nature warms the air up here. But I was impatient to begin my first grow!

Really? What's your trick to that? I use a good bit of electricity growing mushrooms.
Sterilzing alone requires gas or electricity.
How are you dehydrating? The sun and a stiff breeze?
Op... sometimes we have to buffer temps. Just keep an eye on things. An IR temp gun is good to have.

Good idea - maybe I shouldn't have the jars in direct contact with the heating pad (although I am using a thermostat) - I'll raise the jars up a bit. Thanks.

I mean myc does not require electrical help to grow. I don't count sterilizing a media as growing mushrooms you get what I'm trying to say

There should be space betwwen the jars and any heat source.
Put the thermostat prob between the jars and the heat mat to keep the bottoms of the jars from getting too warm.

At 55F, growth will be very slow without additional heating source.

I just buffer the entire room my spawn is when that room is too cold. So here in the winter my house thermkstat is set on 75°. I also use radient space heaters for when it gets really cold.
So, I'm still gonna disagree with you and say that when your spawn area is below 60-65°F, you need to do something t9 buffer and electric is usually the easiest option.
Even if you have your spawn sitting on a shelf at room temp and you're running heat or ac to keep you comfortable... your myc is enjoying that electric comfort by proxy.

Failing an IR gun get a $1 window thermometer and stick it at the bottom of the jars. If the thermometer gets into the upper 70s then find a way to stand the jars off from the heat source or throttle the amount of heat.
A big box lined with 1/4" styrofoam, a 15 watt reptile heating cable and a light bulb will take you far.

I agree that harsh heat in contact with the bottom of the jars would be bad. I'll set the jars on some sort of spacer to lift off of the mat, also move the temperature probe to a more useful spot. Thanks for all the suggestions. I'll follow up with an update soon.

For my first batch of 16 BRF jars, I put half at room temp and half in a cooler with a couple inches of water (with a few drops of bleach to keep the water from getting nasty) and a $20 fish tank heater set at 82 degrees. The jars in the incubator colonized much faster (7/8 were 100% colonized before any of the room temp jars finished), but there's an added contamination risk, and ultimately I stopped using it after that batch because a little extra speed wasn't worth the extra hassle and risk. In OP's case, though, might be worth trying, since at 55 you'll be waiting months for colonization.

I don't think I've ever read about anybody on here having good results trying to use a heating device.

That's mostly why I stopped - it actually worked pretty well in my case, but I figured I just got lucky. The speed difference was really dramatic though. (I live in a northern climate, so the room temp jars were probably on the low side.)

I mean, 10-15 years ago everyone was incubating their BRF cakes. Not saying it's a good method, but some people obviously grew some shrooms.

With you logic you could also say that myc pays rent in your house because it lives in the house where you pay rent. But I wouldn't call that myc is paying rent. If you're heating your house you're doing it for yourself and myc is enjoying that same comfort because you both live in room temp. You're not doing anything extra electrical for the myc that you otherwise wouldn't have done anyway right?
If someone chooses to cultivate mushrooms in 12C outdoor instead of indoor at room temp then it won't be smooth sailing and especially for a noob. It literally takes one cubic foot of space to colonize and fruit 5 BRF cakes. If you don't have a cubic foot of space to cultivate mushrooms then maybe you should wait until you are able to.

The main problem with heating jars is it got the insides too hot, which bred infections.
Im going to heat my PF jars next winter since my room gets below 50F.

And you will heat you FC as well when fruiting? I can not fathom living in a 'room temp' that's below 10C, I'd die. That's almost like a fridge. My room is 25C lol
